Answer:
$22.31
Step-by-step explanation:
At $0.75 per bottle for 36 bottles, Thomas will have sales of ...
$0.75 × 36 = $27.00
His cost is $4.69, so his earnings will be ...
$27.00 -4.69 = $22.31
Thomas will earn $22.31 in profit if he sells all the bottles of water.
_____
He only needs to sell 7 bottles to cover his cost.
Answer:
B
Step-by-step explanation:
We can see in the expression that there are 2 x² blocks, 4 -x blocks, and 3 -1 blocks. Therefore, we can write this as
2 * x² + 4 * (-x) + 3 * (-1) = 2x²-4x-3
Comparing this with each answer, we have
A: x²-2x-4 + x² + 2x-1 = 2x²-5. This is not correct
B: 3x²-7x+1-(x²-3x+4) = 3x²-7x+1 -x²+3x-4 = 2x²-4x-3. This seems correct but we can check the other answers to be sure
C: (2x+1)(x-3) = 2x²-6x+x-3 = 2x²-5x-3. This is incorrect
D: 
. This is incorrect
Answer:
No solution.
Step-by-step explanation:
y = x - 8
y = x² - 2x - 3
Let's find the point where the lines meet;
x - 8 = x² - 2x - 3
x² - 2x + x - 3 + 8 = 0
x² - x + 5 = 0
Applying the quadratic formula method we get,
It will give the value of "x" a complex number hence that graph does not have a solution.
54 is a common denominator between 1/6 and 1/9
Answer:
Algebraically, linear functions are a two parameter family. The parameter a is called the function's y-intercept and the parameter b is called the slope. Together, they completely determine a linear function's input-output behavior. Notice that f(0) = a : The y-intercept is the output when the input is 0.
